How to write an invoice as a freelancer in India (2026)
Freelancers get short-changed on invoicing advice because most templates are written for shopkeepers or SaaS companies. This one is for you — the copywriter in Bhopal, the developer in Kochi, the designer in Guwahati. What to write, when to send it, and how to make sure the money lands in your bank.
Do you need GST registration?
You must register for GST if your annual gross receipts (service revenue) cross ₹20 lakh in a financial year (₹10 lakh for special-category states like Himachal, Uttarakhand, and North-East). Below that, you can operate as an unregistered service provider using only your PAN.
You may voluntarily register even below ₹20 lakh if:
- You mostly bill B2B clients who prefer GST invoices (better for their ITC)
- Your incoming purchases have significant GST (laptops, software, courses) — you can claim ITC
- You bill foreign clients (registration lets you file LUT and avoid tax on exports)
PAN-only invoice — what it looks like
If you're not GST-registered, your invoice is technically a "Bill of Supply" or a simple invoice. It should have:
- Your full name (as on PAN) and address
- PAN number (mandatory if invoice value ≥ ₹2 lakh under section 139A)
- Invoice number and date
- Client's name and address
- Description of services rendered
- Amount (no GST breakup)
- Payment instructions (bank / UPI)
- Signature
- Do NOT write "Tax Invoice" or charge GST — this is a serious violation
GST-registered freelancer invoice
Once you have a GSTIN, every invoice for taxable supplies must be a "Tax Invoice" with all 14 fields under Rule 46. Our GST invoice guide covers this in detail.
Handling TDS deduction by the client
Under section 194J, most Indian clients deduct 10% TDS on your professional fees (technical fees for royalty are 2%). This is deducted before GST. Example:
- Your fees: ₹50,000
- GST @ 18%: ₹9,000
- Invoice total: ₹59,000
- Client deducts TDS @ 10% on ₹50,000 = ₹5,000
- You actually receive: ₹54,000
- You claim the ₹5,000 as TDS credit when you file your ITR
Get a Form 16A from the client each quarter (or download from TRACES using your PAN). Reconcile it with Form 26AS in June before filing ITR.
Retainer vs project billing — pick the right invoice format
Retainer: monthly fixed fee. Send the invoice on the 1st of every month. Description: "Retainer fee for [Month, Year] — content strategy and execution services". Same amount each month, incremental invoice numbers.
Project: milestone-based. Break the total scope into 3–5 milestones. Send one invoice per milestone completion. Description: "Milestone 1 — Discovery & wireframes for [Project X]".
Hourly: attach a time-sheet. Description: "Design consulting — [Client] — [Month] — 42 hrs @ ₹1,500/hr = ₹63,000". Attach a PDF of hours logged.
Foreign clients — the export-of-services trick
When you bill a foreign client and receive payment in convertible foreign currency (USD, EUR, etc.), it qualifies as "export of services" under GST. Two options:
- File LUT (Letter of Undertaking) annually on the GST portal — then bill without GST
- Pay IGST at the applicable rate, claim a refund later — cash-flow disadvantage, avoid this
On the invoice, mention: "Supply meant for export of services under LUT — LUT-ARN [your ARN]. No IGST charged."
How to write the description line — clients pay for what they understand
Bad: "Design work"
Good: "Brand identity design — logo (3 concepts), colour system, typography, brand guidelines PDF — as per SoW dated 12 Jan 2026"
Specific descriptions:
- Reduce disputes
- Show the value you delivered
- Help the client's accounts team book the expense correctly
- Make audit trails smoother 5 years later
Payment terms that get paid faster
- Net 15 for retainer clients you trust
- Net 30 is the Indian standard for B2B
- Net 7 if you have leverage — always ask, worst case they say no
- 50% advance + 50% on delivery for one-off projects
- Late fee clause: "Payments beyond due date attract interest @ 1.5% per month" — Section 15(2)(d) of CGST Act allows this on the taxable value
Sending the invoice — the small details
- Subject line: "Invoice INV/25-26/017 — Anita Design Studio — Due 15 Feb 2026"
- Email body: two lines, mention the amount, the due date, and one thank-you line
- Attach PDF (never editable formats like DOCX or XLSX)
- CC your client's accounts email if you know it
- Send a WhatsApp/Slack ping same day: "Sent the invoice on email, please let me know if you need anything else."
